The Samsung 850 EVO SSDs have performed extremely well in
the HD Tune sequential reading test.

ATTO disk benchmark

ATTO has become a standard tool for measuring the data
throughput of HDDs and SSDs. It measures the reading and writing performance,
using different file sizes and block sizes.

CrystalDiskMark 3.0

Crystal Disk Mark is quite a handy benchmarking application,
as it focuses on the file sizes that can cause a problem on a system drive.

As we can see from the above screenshots, sequential reading
and writing speeds are both very impressive, and random writing performance at
low and high queue depths is excellent.


AS SSD Benchmark

AS SSD benchmark is a benchmarking tool specifically
designed to test SSDs. The application tests sequential reading and writing
performance, 4K random reading and writing performance.

AS SSD benchmark also tests 4K threaded performance. This is
very exciting, as this test is the first available test that I am aware of,
that simulates how a PC operating system actually works. A modern PC and OS,
such as Windows 7/8 does not just run a single thread at a time, it runs many
threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads
simultaneously throughout the test. If this result is good, then you can be
pretty sure the drive will perform extremely well as a system drive.

After the tests complete, AS SSD benchmark derives a total
score for the drive being tested. This is based on all aspects of the test
results, and gives an indication of how the drive is performing overall.

Now let’s look at the result from the Samsung 850 EVO SSD in
the form of a screenshot. All our other comparison drives’ results are
presented in the form of a graph.

As we can see from the AS SSD test run, the Samsung 850 EVO
SSDs have excellent reading and writing performance, finishing this test in
second and seventh place respectively.

Summary:

The Samsung 850 EVO mSATA and M.2. SSDs have performed extremely
well in the basic synthetic benchmarks. Random reading and writing performance
is very impressive. Sequential reading and writing performance is outstanding.
